Answer: maximum height of the football = 176 feet

Step-by-step explanation:

We want to determine the maximum height of the football from the ground. From the function given,

h(t) = -16t^2+96t +32, it is a quadratic function. Plotting graph if h will result to a parabolic shape. The maximum height of the football = the vertex of the parabola. This vertex is located at time, t

t = -b/2a

b = 96 and a= -16

t = -b/2a = -96/2×-16= 3

Substituting t = 3 into the function if h

h(t) = -16×3^2+96×3 +32

=-16×9 + 96×3 +32

= -144+ 288+32

=176 feet

Is (1,2) a solution of 6x-y>3
tangare [24]

Answer:

Yes

Step-by-step explanation:

To determine if (1, 2 ) is a solution of the inequality, substitute the coordinates into the inequality and if satisfied then they are a solution, that is

(6 × 1) - 2 = 6 - 2 = 4 > 3

Since 4 > 3 then (1, 2 ) is a solution

The following is the formula for finding the area (A) of a trapezoid with height (h) and bases (b1) and (b2). A = 1/2h(b1 + b2)
charle [14.2K]

Answer:

<em>Correct choice: B</em>

Step-by-step explanation:

<u>Equation Solving</u>

The area of a trapezoid with height h and bases b1 and b2 is given by:

\displaystyle A=\frac{1}{2}h(b_1+b_2)

We must solve this formula for h.

First, multiply by 2 to eliminate denominators:

\displaystyle 2A=h(b_1+b_2)

Now, divide by b1+b2:

\displaystyle \frac{2A}{b_1+b_2}=h

Swapping sides:

\displaystyle h=\frac{2A}{b_1+b_2}

Correct choice: B

write and solve this equation: Samantha is one year less than twice her brother Jack’s age. If the sum of their ages is 41, how
Rufina [12.5K]

Answer:

Samantha's age = 27 years

Step-by-step explanation:

  • Let Jack's age be = x

As Samantha is one year less than twice her brother Jack’s age.

  • So Samantha's age = 2x-1

As the sum of their ages is 41.

Thus, the equation become

x+2x-1 = 41

3x-1 = 41

3x = 42

Dividing both sides by 3

x = 14

It indicates that Jack's age = 14 years

Therefore,

Samantha's age = 2x-1 = 2(14)-1 = 27 years

Can you show me this step by step please
Leya [2.2K]

Answer:

  clockwise from left, the missing side lengths are 8 m, 13 m, 8 m

Step-by-step explanation:

The perimeter of the figure is the sum of the lengths of its sides. Sides with the same hash mark have the same length, so the perimeter (in meters) is ...

  38 = (3x+1) +(2x) +(9) +(2x)

  38 = 7x +10

  28 = 7x . . . . . . subtract 10

  4 = x . . . . . . . . divide by 7

Then the short sides are ...

  2x = 2·4 = 8 . . . meters

and the long side is ...

  3x+1 = 3·4 +1 = 13 . . . meters

Answer:

When the probe reaches the ocean floor, the horizontal distance of the probe from the team's ship on the ocean's surface will be approximately 1625 meters.

Step-by-step explanation:

tan=opposite/adjacent

tan67.4°=3900/x

2.40=3900/x

cross multiply

2.40x=3900

divide via by 2.40

2.40x/2.40=3900/2.40

x=1625

When the probe reaches the ocean floor, the horizontal distance of the probe from the team's ship on the ocean's surface will be approximately 1625 meters
